How does road marking in horizontal curves influence driving behaviour?

open access: yesEuropean Transport Research Review, 2020
Purpose Given the inconsistent application of various road markings on Czech rural roads, there is a question “How does road marking in horizontal curves influence driving behaviour?” The study objective was to assess how centreline and edgelines ...

CurvAGN: Curvature-based Adaptive Graph Neural Networks for Predicting Protein-Ligand Binding Affinity

open access: yesBMC Bioinformatics, 2023
Accurately predicting the binding affinity between proteins and ligands is crucial for drug discovery. Recent advances in graph neural networks (GNNs) have made significant progress in learning representations of protein-ligand complexes to estimate ...

On b-edge consecutive edge magic total labeling on trees

open access: yesElectronic Journal of Graph Theory and Applications, 2022
Let G = (V, E) be a simple, connected, and undirected graph, where V and E are the set of vertices and the set of edges of G. An edge magic total labeling on G is a bijection f : V ∪ E → {1, 2, …, |V|+|E|}, provided that for every uv ∈ E, w(uv)=f(u)+f(v)+

Visual Analysis of Vehicle Trajectories for Determining Cross-Sectional Load Density

open access: yesTransactions on Transport Sciences, 2019
The goal of this work was to analyze the behavior of drivers on third class roads with and without horizontal lane marking. The roads have low traffic volume, and therefore a conventional short-term study would not be able to provide enough data. We used

The analysis of the implementation of RBL-STEM learning materials in improving student’s meta-literacy ability to solve wallpaper decoration problems using local antimagic graph coloring techniques

open access: yesHeliyon, 2023
The tessellation problem is interesting to study, especially when it is associated with mathematical concepts. In this study, a graph coloring technique will be applied to solve the problem of wallpaper tessellation decoration. The main objective of this

Multipartite Ramsey numbers for the union of stars

open access: yesElectronic Journal of Graph Theory and Applications, 2022
Let s and k be positive integers with k ≥ 2 and G1, G2, …, Gk be simple graphs. The set multipartite Ramsey number, denoted by Ms(G1, G2, …, Gk), is the smallest positive integer c such that any k-coloring of the edges of Kc × s contains a monochromatic ...

On (a,d)-antimagic labelings of Hn, FLn and mCn

open access: yesIndonesian Journal of Combinatorics, 2020
In this paper, we derive the necessary condition for an (a,d )- antimagic labeling of some new classes of graphs such as Hn, F Ln and mCn. We prove that Hn is (7n +2, 1)-antimagic and mCn is ((mn+3)/2,1)- antimagic.

Prevention and Control of Fusarium spp., the Causal Agents of Onion (Allium cepa) Basal Rot

open access: yesHorticulturae, 2022
Fusarium basal rot disease (FBR) is considered a serious threat to commercial onion production in Israel and worldwide. Today, coping means applied in Israel against the disease have limited efficiency and include a four-year crop cycle and disinfecting ...
